Example Embodiment

[0023] The embodiments of the present invention will now be described in detail with reference to the drawings.

[0024] As shown in Figure 1, the working principle of the laser imaging SF6 leakage positioning device of the present invention is: the laser light emitted by the laser 4 passes through the germanium crystal concave lens 3 and then is directed to the device under test 1. At this time, infrared waves will be leaked from the device under test 1. The emitted SF6 gas is absorbed, and the position where there is no SF6 leakage will not be absorbed. The laser light that enters the germanium crystal lens 2 after reflection or backscatter is fed back to the infrared imaging device 5 and forms an infrared imaging matrix distribution 6. This infrared imaging The matrix distribution 6 can be visually displayed on the liquid crystal display 8 after processing and analysis by the microprocessor 7, and can also be converted into a picture format recognized by the computer 10 and sto...

Abstract

The invention provides a laser imaging SF6 leakage positioning device, including a power unit, a laser which is connected with the power unit and is supplied by the power unit, first germanium lens which is arranged before the laser to make the laser pass through, an infrared imaging device which is connected with the power unit and is supplied by the power unit, second germanium lens which is arranged on the front end of the infrared imaging device and makes reflected or backscattered laser pass through the second germanium lens and go into the infrared imaging device, a main processing unit which is connected with the output part of the infrared imaging device and judges the leakage position of SF6 according to the electric image signals output by the output part of the infrared imaging device and a display which is connected with the output part of the main processing unit to display output results. The device can make SF6 leakage air which can not be observed under normal condition visible and clear in standard video display. Detection personnel can fast make sure SF6 sir leakage source through an intuitive image in the display.

Description

technical field [0001] The invention relates to a laser imaging SF6 leakage location device in the field of electric power transmission and transformation; especially for indoor GIS (high-voltage combined electrical switch) or outdoor GCB (SF6 circuit breaker and its A laser imaging SF6 leak location device for gas location leak detection and diagnosis of supporting equipment). Background technique [0002] As a necessary part of the power transmission and distribution process, switchgear is widely used in the power production and management of functional departments such as power plants and power supply bureaus in the power system. In practical applications, whether it is a domestic or foreign switch manufacturer, due to factors such as the production process, sealing process and site environment of the product, there are more or less different degrees of SF6 gas leakage. The specific leakage parts include compartments, Insulators, O-rings, switch insulating rods, secondar...
